Definitions
- the ' whoe ⁇ cle ' invention relates to a method " for " determining a clutch application point in a transmission of a vehicle with a spring-operated clutch system.
- a method for determining or determining the clutch application point is known, in which a speed sensor attached to the transmission is evaluated.
- the transmission is switched to neutral and the clutch is slowly transferred from the open state to the closed state.
- a change in the transmission input speed can be determined. If the clutch is behind the application point, a moment is transmitted with the clutch. This point at which the coupling exhibits discontinuous behavior is referred to as the application point. In a disadvantageous manner, this method can only be carried out when the engine is running. Furthermore, an additional built-in transmission input speed sensor is required, which in particular increases the manufacturing costs.
- a method for determining a clutch application point is also known from EP 0 550 222 A2, which can only be carried out when the engine is running.
- a method for determining or determining the clutch application point in which the injection quantity of the engine is evaluated when the gear is in neutral.
- the clutch is transferred from the open state to the closed state.
- the engine idle controller tries the engine speed regulate constantly. If the load on the engine output side is increased while idling, the engine controller responds by increasing the injection quantity. This increase is used to Detetation- the application point '. Extensive information of the engine are needed 'drive this "encryption" For "in a disadvantageous manner.
- this known method can only be used with the engine running. In a possible failure of communication between the engine and the transmission, this type of recognition not possible.
- the object of the present invention is to provide a method for determining a clutch application point, in which the highest possible availability is ensured, in particular in a cost-effective manner.
- a method according to the invention is proposed in which the clutch application point is adapted as a function of a suitable manipulated variable. It is particularly advantageous with this method that it can also be carried out when the engine is switched off. Furthermore, no additional sensors are required to detect speed signals and / or injection quantity signals. Overall, the method can achieve higher availability and, moreover, cost savings.
- a further development of the invention can provide that the release force provided for actuating the clutch system is used as the manipulated variable.
- the release force acts against a contact pressure which, when the clutch is closed, due to the pretension z. B. a disc spring is specified.
- the coupling application point can be through a common intersection of the
- the course of the disengagement force and the course of the spring force can be determined via the disengagement path.
- the clutch application point is characterized by a discontinuity in the gradient. Therefore, in the method according to the invention, the gradient course of the disengagement force can be determined and the discontinuity can be determined, so that the desired clutch application point is obtained.
- a section is determined in sections before and a gradient provided after the discontinuity. For example, with the. determined gradients and thus corresponding straight lines are determined, the common intersection of which then indicates the point of discontinuity and thus also the coupling application point.
- a further development of the present invention can provide that, in the case of a mechanically actuated disengagement system with the clutch closed, the contact pressure by the Bias of the diaphragm spring is specified. If the diaphragm spring tongues on the release system are now operated, the contact pressure can be reduced by the force on the release mechanism multiplied by the lever. This is represented by the following equation:
- the derivation or the gradient of the release force on the release system shows a discontinuity.
- the transition can be smooth.
- the transition area can also be determined here.
- a further embodiment can provide that the clutch system is transferred from the closed state to the opened state by a suitable actuator system. It is also possible that a release force gradient change is determined by evaluating the manipulated variable and the resulting path on the release system. The determination can of course also from the transition from open to closed state of the clutch. This is possible with hydraulic, pneumatic as well as electrical control of the clutch actuator.
- a hydraulic clutch actuation device with clock valves it can be provided, for example to determine the application point, that the clutch opening clock valve is actuated from the closed state of the clutch with a constant or defined pulse width.
- the clutch closing valve can be actuated when the clutch is open with a constant or defined pulse width.
- the flow at the valve depends on the pressure difference.
- the clutch application point can then be determined by evaluating the detected clutch travel.
- the method according to the invention can also be provided when the clutch actuator is pneumatically actuated. If an electro-pneumatic system for controlling the clutch actuator is provided, the application point can preferably be inferred from the measurements of the path and pressure. If an electrical system for controlling the clutch actuator is provided, the application point can preferably be inferred from the measurements of path, voltage and / or current.
- a typical curve is shown as the diaphragm spring characteristic.
- the contact pressure f ⁇ ⁇ ⁇ r ⁇ begins to decrease when the release force f is released from the release system.
- the disengagement force f disengagement is continuously increased until the contact pressure f anpreBB reaches zero and is therefore equalized. Then there is a balance of forces. This point is coupling point 5.
- Release force and spring force can be measured quantities. However, they can also be calculated from the given properties of the components. reference numeral
